中文摘要	研究分析干旱气候条件下甘肃北山公婆泉盆地天然地下水水化学成分特征,结合水文地质条件与水化学特征P iper三线图表明：研究区存在4种类型地下水,白垩系深层水中钙镁离子含量相对高于其他类型水。地下水氚同位素结合水化学特征较好地区分了水源点的水文地质属性。氢氧同位素表明,该区地下水来源于大气降水,第四系浅层水受到强烈的蒸发作用,发生了一定程度的氧漂移,并影响混合水的同位素组成。最后分析了地下水主要离子的来源,以及地下水形成过程中所受到的溶滤、沉积和蒸发等水文地球化学作用。
英文摘要	In this paper, the chemical properties of groundwater in the Gongpoquan Basin located in the Beishan region, Gansu Province in northwest China under typical arid climate are analyzed. The hydrogeologic settings and the Piper triangular graph reveal that there are 4 types of groundwater in the study area, and the calcium and magnesium concentrations in deep groundwater in the confined Cretaceous aquifer are generally higher than those in groundwater in other aquifers. The hydrogeologic properties of water samples can be identified by the relationships between tritium and the concentrations of other common minerals. Most oxygen and hydrogen isotopes reveal that groundwater in the study area is mainly recharged by permeation of precipitation, but there is somewhat oxygen shift in shallow ＂mixed＂ groundwater due to the violent evaporation and the change of isotopic compositions. Finally, both the provenances of main water ions and the hydro-geochemical effects involving in the rock leaching, deposition and evaporation in groundwater recharge are analyzed.
